Description

DETAILED DESCRIPTION OF THE INVENTION

TECHNICAL FIELD [0001] The present invention relates to an adhesive / substrate system combined for the purpose of attaching and detaching arrangements of image graphics.

BACKGROUND OF THE INVENTION Image graphics are found everywhere in modern life. Images and data for warning, education, entertainment, advertising, etc. have been applied to various indoor, outdoor, vertical and horizontal planes. Examples of image graphics include posters advertising new movies to warning signs indicating steps, but the range is unlimited and varied.

If the length of arranging an image graphic at a target location is limited to a short time,
An image graphic that can be easily replaced is required, and a replacement image graphic is often used in place of the image graphic to be removed. An example of an exchange image graphic is the movie poster described above.

[0004] Easily interchangeable image graphics require both "endurance" when placed on a horizontal or vertical surface and "peelability" when removing it.

[0005] Among the various types of easily interchangeable image graphics are films that include an image on one major surface and include an adhesive area on the opposite major surface. Again, movie posters and other posters are often adhered to one surface. If the adhesive is a pressure-sensitive adhesive and can be easily removed without leaving the adhesive, the poster can be pasted, has a long-lasting power, and is easily removed.

There are many methods for mounting an image graphic film on a substrate.
Image bearing substrates coated with PSA) and mechanically fixed graphics are two typical methods that represent the state of the art. PSA coated substrates typically include PSA coated on a polymer film such as polyvinyl chloride (PVC) or high quality paper. The PSA is protected by providing a silicone-treated release paper.

[0007] Mechanically fixed graphics can take many forms, examples of which include:
Simply stapled printed paper to the desired substrate, nails,
Plexiglas that can be mounted in place by pull, clip or other means ^TM Rigidity such as printed cardboard or rigid polymer sheet material, or cardboard
PSA coating graphic, which can be mounted on the carrier and likewise

As noted, these graphics are converted to magnets or hook and loop fasteners.
It is also possible to mount using small pieces. U.S. Pat. No. 5,196,266 and
No. 5,316,849 (both given to Lu et al.) Include other mechanical fasteners.
Are disclosed. Alternatively, International Patent Application No. US 98/39759
As described in (assigned to Loncar), the hook and loop structure is
Can be printed directly, can be placed on the opposite main surface of the film
.

[0008] Furthermore, special mention must be made of the four systems.

First, in order to manufacture a double-sided sheet, a release liner wound spirally around the sheet itself is often used. If the liner has images or print information, the liner interacts with the adhesive only during storage until use. At the time of placement using the sheet, the printed release liner is discarded. International Patent Application No. WO 97/07492 discloses a method for fixing a picture on a movable photographic carrier using fixing means including a double-sided carrier having different adhesive strengths on both sides. In this application, the picture is fixed to a carrier using a double-sided sheet at a peripheral portion that is a point of the picture.

Second, 3M Post-It ^™ Memoboard 558 (Minnesota Mining and Manuf, St. Paul, Minn., USA)
The acting Company ("3M")) includes an exposed major surface with a "replaceable" adhesive, on which a substrate to which a piece of paper or film can be attached as a memo or note. The relocation of memos on the main surface is
It means that the adhesive is designed to have a low and limited holding force.

Further, as the exposed main surface of the adhesive becomes dirty with dust, oil, or the like, the adhesive cannot remove the dirt and cannot restore the original holding force. In contrast, U.S. Pat.
No. 5,952,133 (assigned to Amos et al.) Discloses a pressure-sensitive display panel. In this case, billboards, display panels or other signage devices are provided with a pressure sensitive adhesive surface, preferably a water-washable tacky elastomer, on a thick elastic backing. However, the signboard seeks to bond all kinds of materials, including pens, keys, paper, small notebooks and various other articles (both lightweight and heavy). Therefore, almost any product is indiscriminately mounted on this pressure-sensitive adhesive surface as far as possible.

Third, sticky vinyl graphics deserve special mention. Since the substrate to which the adhesive vinyl graphic is bonded is limited to an extremely smooth surface such as glass from the viewpoint of its adhesive strength, the adhesive has a very low adhesive holding power. Further, although not provided with a PSA, the adhesive vinyl is generally provided with a release liner to prevent sticking (of the material itself) and adhesion to smooth surfaces such as metal printer equipment.

Fourth, US Pat. No. 5,462,782 (assigned to Su et al.) Discloses a subject adhesive layer that can only be bonded to the same limited number of surfaces as with adhesive vinyl.
This surface is exposed and provided with an adhesive containing stickiness that cannot attract the dust but cannot be cleaned and cannot restore the original adhesive strength. As another system, International Patent Application No. WO
No. 95/06692 (assigned to Fuji) discloses a self-adhesive film that adheres to itself but does not adhere to other materials.

While image graphics using pressure sensitive adhesive surfaces are extremely versatile, they can be subject to a number of limitations. First, due to the inherent viscosity of the adhesive, the graphics cannot be applied smoothly and evenly to the surface. If the graphic is displaced or wrinkled during application, the graphic must be removed and reapplied. In the worst case, the graphics can be corrupted during removal, and the graphics must be replaced with new ones, which can be quite expensive. Examples such as those found in ControlMac ^™ films sold by 3M have been modified to include special adhesives that limit initial adhesion and have limited repositionability. Adhesive repositionability is also described in U.S. Patent No. 5,296,277, issued to Wilson et al. Further, International Patent Application No. WO 94/21742 (assigned to Kobe et al.) Discloses a multi-cycle, refixable, contact-reactive, non-tacky fastener system.

While the initial placement of graphics is much easier with the use of special adhesive formulations, these improved adhesives take specific measures to address wrinkles and other problems that appear after the main part of the graphic has been applied. is not.

In order to easily remove wrinkles, the adhesive is further modified chemically, such as by changing the glass transition temperature (Tg) of the adhesive composition, or physically, such as by using a pattern coating or microspheres. To limit the viscosity. One approach utilizing physical modification is disclosed in International Patent Application No. WO 98/29516 (assigned to Sher et al.). However, this technique introduces a second restriction on the image graphics using the pressure-sensitive adhesive that the adhesive must be able to be bonded to various substrates for the intended use.

In most cases, commercially available pressure sensitive adhesives can be bonded to several types of substrates, but the adhesion will be too high for other types of substrates. Furthermore, if the adhesive is detachably compounded, the situation is exacerbated because the adhesive strength level of the adhesive can be too high, too low, or within an acceptable range. Thus, pressure-sensitive adhesives are often formulated from a compromise in performance, which is often not all optimal for a particular application.

For situations where graphics are applied to different types of substrates, a variety of films with different types of pressure sensitive adhesive formulations may be required to enable that. This creates additional logistic problems for the customer.

Another problem with films that have an image on one major surface and an adhesive area on the other major surface is that they do not contaminate the adhesive with dust or other effects that degrade the desired tack. Care during storage and during installation. To do this care,
A second film or paper is laminated on the bonding surface, and this is used as a protective liner.

SUMMARY OF THE INVENTION The present invention provides a method for displaying an image using a reusable adhesive surface. In this way, a flexible adhesive carrier is obtained that includes first and second major surfaces each substantially coated with an adhesive. The first adhesive surface is designed to bond the adhesive carrier to the substrate, and the second adhesive surface is designed to releasably secure the image carrier to the adhesive carrier. The adhesive carrier is bonded to the substrate on its first surface.

A flexible image carrier is also provided that includes a first imageable major surface and a second major surface adapted to contact a peelable fixed adhesive surface of the adhesive carrier. This image carrier is not adapted to adhere to a substrate. In the method according to the present invention, the image carrier is provided with an image on its first main surface, and is removably adhered to the adhesive carrier by bonding its second main surface to the second main surface of the adhesive carrier. It is. The image carrier is placed on the adhesive carrier for a predetermined period. The image carrier and the adhesive carrier extend with substantially the same dimensions.

[0022] The present specification further provides a method of displaying multiple images using a reusable adhesive surface;
And a method of applying an image to a transparent substrate as seen through the substrate.
In addition, kits of materials specially adapted for use with the methods described above are obtained.

DETAILED DESCRIPTION The present invention provides an adhesive-attachable image graphics system in which an adhesive is provided as a separate component from the image carrier. By separating the components in this way (compared to prior art structures where the image carrier itself had to be coated with an adhesive), it surprisingly expanded its scope of application, production, imaging and application. And the cost of an image graphics system that can be mounted with an adhesive can be potentially significantly reduced.

As mentioned above, the image carrier is flexible and comprises a first imageable main surface and a second main surface adapted to contact the adhesive carrier, but adhered to the substrate. I will not do it. This is in contrast to image graphics that can be installed with prior art adhesives that include an adhesive layer with a release liner that coats the adhesive to avoid unnecessary adhesion during handling. In the system according to the prior art, a defective multi-layer structure is wasted if there is a defect in image formation. The image-forming material according to the present invention is significantly less expensive than prior art structures, and greatly reduces material loss in the event of a defect. In the present system, the cost reduction is particularly significant when a plurality of image carriers are used successively on the same adhesive carrier. By displaying each image carrier on the adhesive carrier after applying the first image carrier, the adhesive material and the corresponding release liner that would otherwise have to be provided using a prior art system without taking this method. Can be omitted. In a preferred system, an adhesive carrier that can be used in combination with about 10 to 50 image carriers in succession is obtained. The more times the adhesive carrier is recycled, the greater the amount saved by the system according to the invention.
In a particularly preferred system, an adhesive carrier is obtained which can be placed on a substrate for one to two years, with a new image optionally being applied every one to two weeks. Furthermore, the handling of the image carrier material according to the invention may be significantly easier than the corresponding prior art structures, since no adhesive or liner layer is required.

In a preferred embodiment, one or both of the image carrier and the adhesive carrier can be reused. That is, one image carrier can be used at another position (or the same position at a different time), and another image carrier can be used and one adhesive carrier can be used. The fact that one or both of the carriers can be reused in this way is a great advantage of the system according to the invention.

Due to the flexibility of both the image carrier and the adhesive carrier, the system according to the invention is easy to handle, transport and store. An image graphic that can be attached with an adhesive can be arbitrarily applied to a substrate having an uneven shape such as a curved surface.

In one embodiment, the present invention is capable of printing an image on an image carrier that is not coated with an adhesive. The image carrier is substantially thinner than the adhesive-coated image carrier because it does not have a release liner to protect the adhesive. Due to such differences in structure, more printing methods, including printing methods that could not be used conventionally because printing could not be performed on the medium backed by the adhesive,
It can be used as an image graphic material that can be attached with an adhesive. In the conventional method for obtaining an image graphic that can be mounted with an adhesive, an adhesive must be provided on the back side of the image graphic. This necessitates the use of a liner, adding to the cost of image graphics. More importantly, the liners used on such image graphics had to have special, usually costly, characteristics that allowed them to pass through the printing facility. Such special requirements are not required in the image graphic display system according to the present invention.

The present invention also has the great advantage that the user can store and use an image carrier that is not lined with an adhesive or liner. The cost of the present image carrier is reduced because it comprises fewer types of materials than in the prior art, thus reducing inventory and shipping costs. Furthermore, the risk of image damage caused by the image coming into contact with the adhesive or its components, or the risk of the adhesive losing its effect due to holding the adhesive longer than its storage life is reduced. Or disappear.

Optionally, an image can be provided on both sides of the image carrier. Alternatively, an image can be provided on the adhesive carrier before applying the adhesive to contact the intended substrate. With such a structure, while the adhesive carrier is arranged at a certain position, an image that is arranged on the substrate can be obtained while the image on the opposite side of the structure can be exchanged. Through the image carrier or if the image carrier is transparent or translucent).

A preferred embodiment according to the present invention is a method of displaying a plurality of images at the same position in succession using a reusable adhesive surface, wherein (a) each of the images is substantially coated with an adhesive. A movable adhesive carrier having first and second major surfaces, the first adhesive surface being designed to bond the adhesive carrier to a substrate, and the second adhesive surface attaching the image carrier to the adhesive carrier. Providing an adhesive carrier designed to be releasably secured to the substrate; (b) adhering the adhesive carrier to the substrate at a first major surface thereof; and (c) an imageable first member. A first flexible image carrier is provided that includes a major surface and a second major surface adapted to contact a peelable fixed adhesive surface of the adhesive carrier, the first flexible image carrier adapted to not adhere to a substrate. (D) forming an image on a first major surface of a first image carrier (E) contacting the second main surface of the first image carrier with the second main surface of the adhesive carrier to removably adhere the first image carrier to the adhesive carrier, Disposing on the adhesive carrier for a predetermined period; and (f) adapted to contact the imageable first major surface and the peelable fixed adhesive surface of the adhesive carrier. Providing a second flexible image carrier including a second major surface and adapted to not adhere to the substrate; and (g) imaging on the first major surface of the second image carrier. (H) removing the first image carrier from the adhesive carrier; and (i) contacting the second main surface of the second image carrier with the second main surface of the adhesive carrier to remove the second image carrier. The second image carrier is detachably adhered to the adhesive carrier, and the second image carrier is placed on the adhesive carrier for a predetermined period. Comprises the steps of advance is arranged, the image carrier and the adhesive carrier to provide a method of extending in substantially the same dimensions.

It should be noted that any steps involved in the method described in the present invention may be performed in any order as long as the preparatory steps essential to another step are performed first. For example, step (c) and step (f) may both be performed substantially simultaneously, since both are steps of manufacturing an image carrier. Similarly, step (d) and step (g) are both image forming steps and are theoretically performed simultaneously even if the second image carrier must be stored for some time before use. And may be performed substantially simultaneously. Because the image carrier is flexible, it can be stored in any rolled up form. Obviously, step (g) cannot be performed before step (f), since step (f) is a preparatory step required to provide the material used in step (g). Since it is desirable that the first image carrier is already at hand and in an applicable state when the adhesive carrier is bonded to the substrate, it is particularly advantageous if steps (c) and (d) are performed before step (b). preferable.

In a particularly preferred embodiment, the first image carrier is provided imageable with a reusable adhesive already mounted. A continuous image carrier can be exchanged for the first image carrier. In this embodiment, the adhesive carrier can be effectively distributed to the substrate while providing a reusable adhesive at a certain position on the substrate.
In this embodiment, there is provided a method of displaying an image using a reusable adhesive, comprising: (a) an image graphics composite material including a reusable adhesive surface and attachable with an adhesive; i) a flexible adhesive carrier comprising first and second major surfaces each substantially coated with an adhesive, the first adhesive surface being designed to bond the adhesive carrier to a substrate; A carrier, the second adhesive surface of which is designed to releasably secure the image carrier to the adhesive carrier; (ii) a first main surface capable of image formation; A flexible image carrier comprising a second major surface in releasable contact with the adhesive surface and extending with substantially the same dimensions as the adhesive carrier; and providing a composite material comprising: b) a step of forming an image on the image carrier on the first main surface of the image carrier; And flop, is provided a method comprising the steps of bonding to a substrate an adhesive carrier in a first main surface of the (c) an adhesive carrier.

As an alternative, the image carrier may be first imaged and then fixed to the adhesive carrier. The composite material thus formed in advance may be supplied to an applicator and adhered to an intended substrate.

The adhesive carrier can be provided with a separate release liner covering both the first and second adhesive surfaces. Alternatively, a single release liner may be used, and each carrier may be rolled up on itself, utilizing both sides of a single release liner for one adhesive carrier. Different treatments can be applied to both sides of the liner to provide a purposeful release characteristic so that the first adhesive surface can be exposed and applied to the substrate before exposing the second adhesive surface and fixing the image carrier. You may. In another selective delivery system,
It is also possible to supply the adhesive carrier to the applicator as a carrier pad with a single release liner arranged between two adhesive carriers.

In another embodiment of the present invention, there is provided a method of displaying an image through a substrate (eg, a window) utilizing a reusable adhesive surface. The method comprises the steps of: (a) providing a transparent or translucent flexible adhesive carrier including first and second principal surfaces each substantially coated with an adhesive, wherein the first adhesive surface has an adhesive; Providing an adhesive carrier designed to bond the carrier to the substrate, wherein the second adhesive surface is designed to releasably secure the image carrier to the adhesive carrier; and (b) the adhesive. Adhering a first major surface of the carrier to a transparent or translucent substrate; and (c) a first major surface imageable and adapted to contact a peelable fixed adhesive surface of the adhesive carrier. Providing a flexible image carrier including a second major surface and adapted to not adhere to the substrate; and (d) preventing the image from transferring to the adhesive carrier when removed from the adhesive carrier. Then, a step for forming an image on the first main surface of the image carrier is performed. (E) the image carrier is detachably adhered to the adhesive carrier by bringing the first main surface of the image carrier into contact with the second main surface of the adhesive carrier, and the image carrier is adhered for a predetermined period. And placing the image carrier and the adhesive carrier in substantially the same dimensions.

Like the method described above, this method can also be used for the continuous use of a plurality of image carriers.

An image is provided so that the image does not transfer to the adhesive carrier when removed from the adhesive carrier. By using a high quality ink or image forming material and / or by using a protective overlaminate material, images that do not move can be obtained.

Optionally, images may be provided on both sides of the image carrier to enable two different image displays from the same structure.

In a particularly preferred embodiment, the adhesive carrier is removable from the substrate without tearing. Thereby, the adhesive carrier can be easily removed from the substrate,
Thereafter, the substrate may be restored to its original state, or may be prepared with a new adhesive carrier for the next period of image display.

In another particularly preferred embodiment, the image carrier can be removed without distortion or breakage and reapplied to the adhesive carrier. In this embodiment, in particular, the image carrier can be reused at another time or location.

In a particularly preferred embodiment, the adhesive on the second adhesive surface is washable. As used herein, a "washable" adhesive is one that regains at least some of its used surface adhesion by treating it with a suitable cleaning solution (such as water or soapy water) to remove materials that are harmful to adhesion. An adhesive that can be used. After multiple uses, the adhesive may become soiled or lose tack for other reasons. Washing the washable adhesive removes materials that degrade the surface's adhesive performance, restores the surface's adhesive strength, and allows it to be further used to adhere the image carrier to the substrate.

In a preferred embodiment of the present invention, the substrate is a front panel of a back-lit optical display. Therefore, the system obtained by the present invention displays an image using a reusable adhesive under severe conditions in which the image is illuminated from behind by the adhesive. Examples of such displays include windows with light sources behind them and other transparent or translucent substrates. It is more preferable that this display is a light box type display such as an example frequently used for advertisements in shopping centers and airport terminals. In a preferred embodiment of the present invention, the adhesive carrier and the image carrier are provided as transparent materials. This embodiment is particularly suitable for window-type displays or light-box displays that diffuse light using another material. Alternatively, the adhesive carrier and the image carrier can be selected to be transparent or translucent, respectively, to make them suitable for mounting on a front panel of a back illuminated light display. If both the adhesive carrier and the image carrier are transparent, separate light diffusers may be provided and used in the light box. If only one or both are translucent, the adhesive carrier and / or the image carrier itself may act as a light diffuser, eliminating the need for additional diffuser films or materials.

Having both carriers of a particular size is particularly suitable for use in the present invention. That is, the dimensions of the image carrier and the adhesive carrier are preferably 1/8 to 3 meters in width and 1/8 to 3 meters in length, and are 1/2 to 3 meters in width and 1/2 to 3 meters in length. It is more preferable if the width is 1 to 3 meters and the length is 1 to 3 meters.

The ability to provide high quality image graphics that are easily interchangeable is a particular advantage. Thus, the image carrier is transferred using a method selected from the group consisting of colorant transfer, ink jet printing, screen printing, offset printing, flexographic printing, laser printing, electrophotographic printing, electrostatic transfer printing and combinations thereof. It is preferable to form an image. Suitable images are obtained by high quality, four color, high resolution imaging techniques. The resolution of the image is preferably 200 dpi or more, more preferably 300 dpi or more, and most preferably 500 dpi or more.

A particularly preferred embodiment of the present invention is for use in a rotating billboard system comprised of multiple components. The advertising bulletin board is configured by, for example, aligning a plurality of panels to form a flat image surface. Each panel is actually one side of a three-sided, elongate component, for example. When the components of the three-sided advertising bulletin board are rotated, the second main surface of each component is aligned to form a second flat image. Similarly, turning the component a second time aligns the third side of the component to form a third flat image. Finally, if it is rotated once more, it returns to the first image and enters the eyes of the viewer.

Both main surfaces of the adhesive carrier can be coated entirely with an adhesive to maximize the adhesion of one main surface to the substrate and the other main surface to releasably secure the image carrier. To do. If the carrier itself is an adhesive, there is no need to coat another adhesive material on the surface. Since the entire surface of the adhesive carrier exhibits adhesive performance, it can be said that the surface is covered with the adhesive.

In one embodiment of the invention, the versatility is such that a variety of image carriers can be adhered to, even when repeatedly installed, without losing guaranteed utility for a desired duration and environment. First, the adhesive surface on the adhesive carrier can be selected.

In another embodiment of the present invention, the adhesive contact surface of the image carrier and the image carrier contact surface of the adhesive carrier are selected to be compatible to ensure a specific duration and a specific environment. Practicality can be maximized.

In yet another embodiment of the present invention, the adhesive carrier can be selected such that it adheres only to the specific image carrier material and does not adhere to other image carrier materials.

Another advantage of the present invention is that if a suitable image carrier is used in combination with a suitable adhesive carrier, the adhesive carrier can be easily set on the substrate at one time and the image carrier It is easy to remove the image carrier from the adhesive carrier without leaving the adhesive, by setting it on the carrier multiple times. In other words, the image graphic adhesive system according to the invention is designed such that, among the various compositions of the image carrier, only specific image carriers are adhered to the peelable fixed adhesive surface of the adhesive carrier. Can be.
Furthermore, in the interaction of the image carrier and the adhesive carrier designed in this way, the image carrier which is inappropriate in the extreme case does not adhere to the adhesive carrier at all, or is inappropriate in the other extreme case. It can happen that the perfect image carrier permanently adheres to the adhesive carrier. In either case, if an attempt is made to adhere an inappropriate image carrier using an adhesive carrier, the substrate holder will know that it was not the correct use. For example, a media advertising company may either lend advertising or promotional surface space to provide a purposeful image carrier using the image graphics adhesive system according to the present invention, or none at all. can do.

These and other features and advantages of the present invention will become apparent from the following description of embodiments thereof, taken together with the drawings.

Image Graphic Adhesive System FIG. 1 illustrates elements of an image graphic adhesive system common to various embodiments of the present invention. The image graphics adhesive system 10 includes an adhesive carrier 12 permanently bonded to a substrate 14 of variable thickness, on which an image carrier 16 is releasably adhered.

The adhesive carrier 12 fixes the image carrier 16 to the substrate 14 in a releasable manner. The adhesive carrier 12 has an adhesive surface 22 for permanently bonding the adhesive carrier 12 to the substrate 14 and a transparent, translucent or opaque adhesive for ensuring the permanent integrity of the adhesive carrier 12 located on the substrate 14. It can comprise a agent preservation layer 24 and an adhesive surface 26 for releasably securing the image carrier 16 so that the image carrier 16 can be repositioned or removed. Alternatively, if the integrity of one or both adhesives is sufficient to cover the surface area of the substrate 14 with the image carrier 16, the adhesive carrier 12 may have
With only one adhesive surface 22 and 26, the adhesive security layer 24 can be omitted. Alternatively, the two surfaces 22 and 26 of the adhesive carrier 12 may be 1 if the substrate has an adhesive capability that allows the substrate to be permanently adhered and the image carrier 16 to be repositionably adhered. Only one type of adhesive formulation can be included.

The image carrier 16 has an adhesive contact surface 32 that removably adheres to the adhesive surface 26,
A transparent, translucent or opaque adhesive security layer 24 that ensures the permanent integrity of the image carrier 16 on the adhesive carrier 12, and an imageable surface 36 on which image graphics (shown collectively as 40) can be printed. Can be provided. Alternatively, if the integrity of the adhesive contact surface 32 and / or the imageable surface 36 is sufficient for the surface area of the substrate 14 to be covered by the image carrier 16, the image carrier 16 With only the adhesive contact surface 32 and the imageable surface 36, the separate security layer 34 can be omitted. Alternatively, the image carrier 16 may be provided with an acceptable adhesive contact surface 3 if acceptable to the skilled artisan.
It can contain only one type of synthetic formulation that provides both 2 and the imageable surface 36.

The embodiment shown in FIG. 1 is based on the prior art which includes an adhesive surface facing the image, since the adhesive surface 26 is not formed on the image carrier 16 but is part of the adhesive carrier 12. Different from image graphic film. Further, the image graphics adhesive system according to the present invention intervenes between the adhesive surface 26 and the adhesive contact surface 32 with a new adhesive interface specifically designed for use in a particular duration and environment. .
Thus, the image graphics system 10 includes an adhesive carrier 12 and an adhesive carrier 12 where the interface between the adhesive surface 26 and the adhesive contact surface 32 plays an important role in the performance of the system 10 to enable multiple placements and peels. This is a combination with the image carrier 16. In addition, the interface between the adhesive surface 22 and the substrate 14 is also kept in a controlled state while the adhesive carrier 12 is permanently adhered to the substrate 14 so that the adhesive carrier 1 can be removed even when the image carrier 16 is removed.
It is important to keep the state of bonding 2 to the substrate 14.

An important factor in the difference between the adhesive strength to the substrate and the adhesive strength to the image graphic is that the adhesive strength to the substrate is larger than the adhesive strength to the image carrier 16. The description of the unequal peel adhesion described below applies not only to the examples illustrated in the drawings, but also to all preferred embodiments of the present invention exhibiting this unequal peel adhesion.

The interface between the image carrier 16 and the adhesive carrier 12 and the adhesive carrier 12 and the substrate 14
One way to design the interface between is to utilize the standard 90 ° peel adhesion taught in DIN EN 28510 (part 1 = 90 °, part 2 = 180 °) and is specified herein. 9 for each interface using peel rate, substrate and dwell time
The purpose is to compare the peel adhesion at 0 °.

When a silicone-treated image carrier was used, a 180 ° peel test was used as described in the examples below. This test was employed because 90 ° peeling on these systems resulted in very low and hardly measurable measurements. The most common 180 ° peel for siliconized surfaces gives measurable higher values than 90 °. The user of the image graphic system according to the present invention preferably detaches the image carrier 16 from the adhesive carrier 12 at any angle of 20 ° to 180 °, so that the image carrier 16 can be peeled at any angle of 20 ° to 180 °. It is preferable that the relationship of surface peeling be appropriate.

One feature of the image graphic adhesive system according to the present invention is that after a dwell time of about 24 hours, the peel adhesion at the interface between the adhesive carrier 12 and the image carrier 16 increases with the adhesive carrier 12 and the substrate. 14 is smaller than the peel adhesive strength at the interface between them. After a dwell time of about 24 hours, 20 ° to 180 ° at the interface between the adhesive carrier 12 and the substrate 14 20 ° to 180 ° as a ratio to the peel adhesive strength at the interface between the adhesive carrier 12 and the image carrier 16 180% peel adhesion is about 0.1% ~
Preferably it is about 90 percent. As the above-mentioned range approaches 0.1%, a very strong and non-detachable surface bond is obtained in combination with a siliconized image carrier. As the above-mentioned range approaches 90%, a peelable adhesive bond to the substrate 14 is obtained in combination with the relatively strong adhesive bond between the image carrier 16 and the adhesive carrier 12.

In other words, based on the peel adhesive force between the adhesive carrier 12 and the substrate 14, which is regarded as permanent fixing, the ratio of the peel adhesive force between the adhesive carrier 12 and the image carrier 16, The image carrier 16 can be detachably attached to and detached from the adhesive carrier 12.

In the measurement after the elapse of the residence time of 24 hours, the ratio is preferably from about 1 to about 80% in order to facilitate attachment and detachment while maintaining sufficient adhesive strength at the time of use.

The adhesive force at the interface changes over time. Thus, for a residence time of about 14 days, to obtain the expected performance at each interface, the choice of adhesive and the method by which the adhesive interacts with the surface with which the adhesive contacts during the elapsed time. Based on that, the ratio is about 0.1 to about 90%.

Since the actual value of the peel adhesion may vary for different substrates, adhesive carriers and image carriers, the differential interface adhesion is expressed as a percentage for both a 24-hour residence time and a 14-day residence time. Expressed by However, those skilled in the art will recognize that based on the type, duration and environmental conditions of the substrate, both the adhesion of the adhesive carrier 12 to the substrate 14 and the adhesive force of the image carrier 16 to the adhesive carrier 12 that can be peeled off are determined. Thus, the choice of materials for the adhesive carrier and the image carrier can be changed.

Further, based on the selection of the peeling adhesive force for the purpose of bonding or the peeling adhesive force for the purpose of fixing, it is possible to select an adhesive carrier and a material for an image carrier for obtaining a heterogeneous interfacial adhesive force. . Those skilled in the art who know the desired range for the ratio of the peel adhesive force, starting from the peel adhesive force of the peelable fixed adhesive surface 26 or the peel adhesive force of the fixing surface 22 included in the adhesive carrier 12, may be used as a specific material. An image graphic adhesive system suitable for use can be designed. Thus, the "reference" for the 20 to 180 degree peel adhesion can begin at the bonding surface 22 or surface 26.

The adhesive contact surface 32 of the image carrier 16 is a surface designed to releasably adhere to the adhesive surface 26 in the system 10. Depending on the quality of the adhesive selected for the adhesive surface 26, the material of the adhesive contact surface 32 can be varied in various ways depending on the desired use parameters such as duration and environment. Whatever material the adhesive surface 26 is, it is preferred to identify the adhesive contact surface 32 of the image carrier 16.

For example, one embodiment of the adhesive surface 26 is not tacky when in contact with most materials, but is releasably securable to the adhesive contact surface 32 of the image carrier 16 at its image interface. It can be described as an adhesive. In other words, the adhesive surface 26 is differentially adhesive and has little or no tack to adhere other materials that do not match the performance of the adhesive contact surface 32.

The adhesive surface 26 is applied to the adhesive surface 26 for a long time at the image interface of the adhesive contact surface 32.
It is preferred to have reusability, high internal strength, low dust absorption and aging properties that allow it to be repeatedly fixed to 6. If possible, it is desirable to have good cleanliness. The ability to be repeatedly secured should provide a good bond at the image interface between the adhesive surface 26 and the adhesive contact surface 32 while allowing the adhesive surface 26 to be easily attached and detached without damage. The combination of the adhesive carrier 12 and the image carrier 16 must produce a high quality image graphic produced either manually or by mechanical means.

An advantage of the present invention is that the adhesive and the film can be separate components in this system, so that the most effective method can be selected for a particular application. The pressure-sensitive adhesive selected for the surface 22 is applied to the adhesive carrier 12 on the substrate 1.
4 can be designed to have maximum adhesion. On the other hand, the bonding surface 26
The adhesive selected for is either indiscriminately high tack, differentially high tack, or little or no tack, depending on the duration and environment used. Can be

It appears that system 10 has one limitation. That is, the system 10 in certain embodiments requires two applications, the application of the adhesive carrier 12 to the first substrate 14 and the application of the image carrier 16 to the second adhesive carrier 12. The disadvantage of having to make these two applications is a disadvantage, which can be reduced by the following factors. First, it simplifies each application. If the alignment of the adhesive carrier 12 does not go well during the application, this material can be trimmed into squares to a suitable size. If wrinkled, it can be cut and replaced. Second, lowering the adhesion of the image carrier 16 to the adhesive carrier 12 (compared to the adhesion of the adhesive carrier 12 to the substrate 14) allows the graphic to be easily applied without introducing air bubbles, Removal and reapplication is also easier. This makes this step very fast.
Third, the system can be effectively used for image graphics where the adhesive carrier 12 is applied only once, but the image carrier 16 is applied and removed multiple times each time the graphic is changed. In this way, the above two applications are performed only at the first time of arranging the graphic. Thereafter, only the image carrier 16 is applied. Fourth, since the attachment / detachment of image graphics is easy and controlled, graphic exchange time can be greatly reduced. Thus, as the number of graphics exchanged increases, the time advantage of this system becomes more pronounced.

Another advantage of the system according to the invention over prior art image graphics in which the imaged film is adhesive-backed is that the cost of replaceable graphic systems is reduced due to the low waste of the system 10. Potentially suppressed.
With conventional adhesive-coated graphics, customers had to purchase three components for each application: a graphic film, a pressure-sensitive adhesive, and a high quality liner. The liner is discarded when applied and the pressure sensitive adhesive is discarded when removing the graphic. In the system 10, the adhesive carrier 12 is provided with a liner, which must also be disposed of at the time of application. However, since no printing process is performed on the adhesive carrier, a high-quality liner may be required for dimensional stability, but the cost of the liner for the adhesive carrier 12 is significantly lower. Such a two-layer construction of the adhesive carrier 12 appears to require slightly more material than prior art graphic prior art PSAs, but this uses this system as a single application system. Only if you do. The overall system 10 material is saved when the graphics are changed. That is, only the image carrier 16 without adhesive or liner is discarded and replaced with a new image carrier without adhesive or liner. The adhesive is reused at the same point. In addition, the customer can save money or focus on purchasing higher quality film or high resolution image graphics, since the customer only needs to purchase another image carrier 16 for the next graphic.

As compared to mechanically fixed graphics, system 10 has important and advantageous properties. That is, because of the small thickness of the system 10, it is preferred that it be more compliant than the prior art pressure sensitive adhesive film graphics. In contrast,
Mechanically fixed graphics have the disadvantage of being relatively thick, bulky and difficult to handle. Graphics using frames or rigid substrates can only be applied in a flat state. Even micromechanical adhesive systems such as hook and loop are significantly thicker than pressure sensitive adhesive graphics. For this reason, mechanically fixed graphics do not allow the bonded graphic to appear "painted" in most applications. The system 10 preferably has the advantage of keeping the thickness low so that a high quality pressure sensitive adhesive-based graphic can appear "painted". Preferably, the overall thickness of the image graphics is less than 20 mils. More preferably, the overall thickness of the image graphics is less than 10 mils.

A second advantage of the system 10 over graphics, such as hook and loop systems, or mechanical fasteners, such as staples, is that the system 10 can be suitably used for backlit graphics applications. Graphics that are mechanically fixed as described above are very expensive for this application, are too thick to transmit light, or transmit light due to the intermittent density of the structure (ie, hook and loop). Are not uniform, and good performance cannot be obtained. A preferred embodiment of the system 10 has the advantage that light can be transmitted uniformly in both layers.

Application of the Prior Art In a preferred embodiment of the invention, the system is provided in a relatively low-cost configuration utilizing a prior art image carrier. The materials can be selected so that the system can be used under environmentally harsh conditions or under more controlled and less severe conditions.

The use of the image graphic adhesive system 10 in the application of the prior art is subject to the harsh environment and therefore the expected durability for fixing the adhesive carrier 12 to the substrate 14, and the attachment / detachment or repositioning Image carrier 1 releasably adhered by the time
It is necessary to have expected durability for the adhesive carrier 12 of No. 6. The duration of use of the image carrier 16 in applications of the prior art, when used in harsh environments, is from about 1 day to about 1 year, preferably from about 1 week to about 3 months. A harsh environment can be outdoors or indoors where intense chemicals are present in the atmosphere, where UV light is present, or where the humidity is at a limit, or where the relative humidity has a humidity limit or marginal change. is there.

“Application of the prior art” refers to the use of an image carrier, such as untreated paper or film, that depends on the inherent release characteristics. This kind of material is not easy to rearrange,
A greater force is required for attachment and detachment as compared to an image carrier provided with a special coating that promotes repositionability and easy attachment and detachment. The prior art applications are not well suited for applications that do not create wrinkles and contain bubbles, especially for inexperienced users. However, the prior art application allows the use of paper or uncoated film as the receiving medium for image graphics and is very suitable for inexpensive but high resolution image graphics. The application of the prior art is also suitable when the image carrier needs to be reliably adhered to the adhesive carrier.

Preferably, the imageable surface 36 can be adapted to accept a particular type of printed image graphic 40 by differences in colorants, distribution, and the like. Aging properties and environmental resistance are important. In harsh surroundings, the image must be durable. That is, a colorant mainly composed of a pigment is used instead of a dye or another colorant. Paper image carriers are less preferred. However, non-stripping coated papers and films are also suitable in harsh environments, because of cost and because less robust materials are needed to withstand the effects of the environment.

Easy Application To use the image graphic adhesive system 10 in a harsh environment, the expected durability and adhesive strength of the adhesive force of the adhesive carrier 12 to the substrate 14 before peeling or repositioning. It is necessary to have the expected durability of the image carrier 16 releasably adhered to the carrier 12. Since the image carrier 16 is peeled off from the adhesive carrier, the feature of this system 10 is to provide a coating or film on the surface of the image carrier 16 which comes into contact with the adhesive carrier 12 while facilitating peeling and repositioning. It is that you are. The durability of the image carrier 16 is from about 1 day to about 6 months, preferably from about 1 week to about 3 months.

Detachable pressure-sensitive adhesives are described as possible adhesives.

With the use of transfer sheets 9458 and 966, the adhesion of a transfer adhesive essentially comprising one type of adhesive composition to an untreated substrate is compared to an image carrier comprising an adhesive repellent release composition. Because they are much higher, these sheets can function as the entire adhesive carrier 12.

In other words, the system can be applied for industrial and consumer use by those skilled in the art in any form conceivable taking advantage of the ease of installation and removal.

[0146] These and other examples will become apparent from the following test examples.

Test Method 90 ° Peeling Adhesive Strength For all of the examples, a 90 ° peeling adhesive strength test was performed on (1) the bonding strength of the adhesive carrier to the substrate and (2) the bonding strength of the image carrier to the adhesive carrier. . This test is based on DIN (Deutsche Industry Norm EN 2
8510 Part 1). The peeling speed is 300 mm / min,
The material width to be peeled was 2.54 cm.

180 ° Peel Adhesion The bonding state of the adhesive was prepared as described above with a 90 ° peel adhesion. The peel force of the silicone-treated image carrier from the adhesive layer was set to 2.8 m / min DIN (Deu).
tsche Industry Norm EN 28510 Part2)
Was measured at a high ratio.

In both peel adhesion tests, three samples were measured instead of five as specified in the DIN test method. All samples were overrolled at a rate of 300 mm / min. This is not specific to the DIN test method. The residence time and the choice of the substrate will vary according to the following examples.

EXAMPLES Example 1 A painted sheet metal signboard designed for the display of advertising graphics was selected as the substrate. The two surfaces used for mounting the graphics were painted steel and had dimensions of 85 cm x 60 cm.

From No. 3M Company to Tape No. 9415 High Tack
/ Low Tack Double-Coated Tape Available on both sides, a highly adhesive acrylic PSA was applied to one side and a low-adhesive acrylic PSA was applied to the other side. Double-sided adhesive sheet DIN A4 (21 cm × 29. 7cm)
The sheet was laminated and covered on a part of one of the two surfaces included in the advertising bulletin board. The sheet, available in roll form with one liner applied to the low tack side of the sheet, was rewound and cut to size. The high tack side without the liner was applied to the painted metal surface using a rubber coated roller. The liner was removed from the low tack side. Write a hand-written message and double-sided glue a piece of reusable notepad paper (50 g, available from Landre of Vianen in the Netherlands as No. 36740008) with the same dimensions as the exposed adhesive on the advertising board The agent sheet was applied by hand to the low tack side.

After 24 hours, the paper graphic could be easily removed and repositioned from the adhesive surface. Due to the low restoring force of the paper, the edges did not turn up when removed from the adhesive. The edge did not rise after optimal use. After storage at room temperature and ambient humidity for several weeks, the double-sided adhesive sheet was removable from the substrate.

The peel adhesive strength of the adhesive carrier from the substrate and the peel adhesive strength of the image graphic from the adhesive carrier were measured by a 90 ° peel adhesive strength test (performed based on the method described in the above test method). I checked.

Comparative Example 1 Example 1 was repeated, except that the low tack side of the double-sided adhesive sheet was applied to a painted metal substrate. This was done by first applying the second liner to the high tack side, peeling the liner from the low tack side, and applying the exposed adhesive to the painted metal substrate. Subsequently, the liner was removed from the high tack side and the paper was applied to the high tack side of the adhesive sheet.

After a dwell time of 30 seconds, the paper image graphics could not be removed and broke while trying to remove the paper. When the paper was to be removed from the high tack side of the sheet, the low tack side of the double-sided adhesive sheet was partially raised from the substrate.

Example 2 One sheet of paper suitable for use in a black-and-white photocopier (FAVORIT X, No. 936)
Example 1 was repeated, except that the image was printed using a photocopier at 80 g), available as 6/080/05/04. The paper with the photocopy image was used as an image graphic.

After removing the liner, the image graphics were then manually laminated to the exposed low tack side of the double-sided adhesive sheet. After 24 hours, the printed paper graphic was detachable from the adhesive surface without raising the double-sided adhesive sheet from the substrate.

Example 3 One sheet of paper (FAVORIT X, No. 936) suitable for use in a laser printer
Example 1 was repeated except that the image was printed using a laser printer at 80 g), available as 6/080/05/04. The printed paper was used as an image graphic.

After removing the liner, the image graphics were then manually laminated to the exposed low tack side of the double-sided adhesive sheet. After 24 hours, the printed paper graphic was detachable from the adhesive surface without raising the double-sided adhesive sheet from the substrate.

Example 4 A three-layer film including a core layer of cellular polypropylene, Mobil Pl
Image graphics by printing a red 3M logo using one-color sheet offset printing on a printable film containing white biaxially oriented polypropylene (BOPP), 60 μ thick, commercially available as LABELYTE 60 LL 247 from Astics. Example 1 was repeated except that was formed. This image was applied to the film side which was made suitable for printing by corona treatment. The image graphics were applied with the unprinted side glued to the low tack side of the double-sided adhesive sheet.

Test results have shown that after application, the image graphics, including the printed film, can be easily removed and repositioned. The double-sided adhesive sheet did not protrude from the substrate when the film was attached or detached, and the film was cleanly removed from the adhesive surface. After removal, no adhesive remained on the image graphics and the edges of the film did not turn up.

Example 5 3M with 100 micron thick plasticized PVC backing and acrylic PSA
A 5 micron layer of primer was coated on the non-adhesive side of the Scotchcal ^™ Film 3500. 3M detachable transfer adhesive 9449 was laminated on the film which had just been prepared and which had been subjected to a primer treatment, to prepare a double-sided adhesive sheet.

As described in Example 1, this double-sided adhesive sheet was applied to an advertising bulletin board with the original Scotchcal ^™ adhesive having high tackiness facing the substrate.

OPUS No. 1 from Smurfrit Condat (Finland). 13
Offset printing was performed on 115 g of matte graphic paper for offset printing available as 701150510 to prepare an image graphic. This image graphic was applied to the exposed adhesive.

This image graphic was detachable from the double-sided adhesive sheet. This double-sided adhesive sheet was also detachable from the FOREX substrate, but required a very large force.

Comparative Example 2 A mixture layer of a first aqueous acrylic pressure sensitive adhesive available from BASF as Acronal 35D was prepared from a 36μ polyethylene terephthalate film commercially available from Hoechst as HOSTAPHAN RN 36 and corona treated on both sides. First, a double-sided adhesive sheet was prepared by coating on one side. This adhesive was first concentrated with 1% by weight of Collacral PU manufactured by BASF,
This was applied to the film by knife coating at a dry coating thickness of about 50 microns and dried in a forced oven at 100 ° C. for about 10 minutes. A release liner was laminated on the dried adhesive layer. The adhesiveness of this adhesive layer was reduced.

[0177] The other side of the sheet thus coated on one side was coated with an aqueous acrylic pressure-sensitive adhesive available as Acronal A 213 S from BASF. This was concentrated as described above, coated and dried to obtain a double-sided adhesive sheet. The second side included in the sheet was more sticky.

This double-sided adhesive sheet was applied to a substrate with its high tack side facing the substrate.

OPUS No. from Smurfrit Condat (Finland). 13
Offset printing was performed on 115 g of matte graphic paper for offset printing available as 701150510 to prepare an image graphic.

The image graphic was adhered to the exposed low tack adhesive layer. However, the paper graphic did not adhere to the adhesive. Because this image graphic dropped spontaneously in its vertical position, unable to support its own weight,
It can be seen that the peel adhesion value of the image graphic to the adhesive carrier was too low.

[0202] 75g Release from Lohjan Paperi (Finland)
The image graphics were prepared by handwriting a message with a felt pen on a siliconized paper available as PMC (Standard Low Peel Level). The paper was only siliconized on one side, and the handwriting was on the non-siliconized surface of the paper.

Next, this image graphic was adhered to a double-sided adhesive sheet. At this time, the silicone coating of the image carrier was directed to the high tack side of the double-sided sheet.

[0204] This image carrier was easily removable on highly sticky surfaces without tearing or distortion of the image graphics. When the graphic was attached and detached, the double-sided adhesive sheet remained adhered to the substrate, but a low-tack adhesive was applied to the substrate. This double-sided adhesive sheet was detachable from the substrate.

The adhesive strength of the adhesive carrier from the substrate was quantitatively examined by a 90 ° peel adhesive strength test (performed based on the test method described above), and the image graphic was peeled from the adhesive carrier. The adhesive strength was quantitatively examined by a 180 ° peel adhesive strength test (performed based on the method described in the test method described above).

Example 15 Example 14 was repeated, except that an image was formed on the non-silicone-treated side of the siliconized paper image carrier using a photocopier. The results obtained were essentially the same as in Example 14.

Example 16 Example 14 was repeated, except that an image was formed on the non-silicone-treated side of the silicone-treated paper image carrier using a laser printer. The results obtained were essentially the same as in Example 14.

Comparative Example 3 Example 14 was repeated except that the double-sided adhesive sheet was applied to the substrate with its high tack side facing the substrate.

[0210] The image graphics were placed on the exposed low tack side and were not adhered. When the assembly was placed in a vertical position, the graphic failed to support its own weight and separated from the adhesive without any external peel force. The double-sided adhesive sheet could be cleanly removed from the substrate, but required a very large force.

Example 18 75 g Release from Lohjan Paperi (Finland)
Example 14 was repeated except that the second siliconized paper, available as PMC MR30 (high release system), was screen printed on the non-siliconized side and used as an image graphic.

Next, the image graphics were adhered to the double-sided adhesive sheet with the silicone coated side of the image carrier facing the high tack side of the double-sided adhesive sheet. The close contact allowed the image graphics to be firmly bonded to the substrate.

This image carrier could be removed cleanly from the adhesive surface without causing tearing or distortion of the image graphics. Upon removal of the graphic, the double-sided adhesive sheet remained adhered to the substrate, which was also removable from the substrate.

Example 19 Image graphics were obtained from Akrosil (Heerlen, The Netherlands)
Example 14 was repeated except that it was made of 90 g of paper available as ox 90 CL. An image graphic prepared by inkjet printing on the non-siliconized surface of the paper was again applied to the high tack side of the double-sided adhesive sheet as in Example 14. The image quality and handleability of the graphic prepared on this paper was excellent for the intended use (for use in Example 14).

This image carrier could be easily attached to and detached from the adhesive surface without causing tearing or distortion of the image graphic. When attaching and detaching the graphic, the double-sided adhesive sheet was still adhered to the substrate, but it could be similarly attached to and detached from the substrate.

A transparent double-sided adhesive sheet was prepared by coating on the printed BOPP film. At the same time, only two different syrups containing a mixture of acrylic polymer and monomer were coated to a thickness of 100 microns on each side of the BOPP film by knife coating.

The syrup used on one side contained 2.0% tetrapropylene glycol diacrylate (TPGDA) crosslinker in addition to the components described above. The syrup used on the other side contained 0.5% TPGDA crosslinker. The adhesive strength of the adhesive layer having a low cross-linking agent content was higher. A low crosslinker (0.5%) syrup was coated on the side of the BOPP film with the printed image. Next, the syrup-coated BOPP was protected between two siliconized polyethylene terephthalate (PET) liners and applied to EP 0733.
The adhesive syrup was cured using UV radiation to create a pressure sensitive adhesive layer as described in US Pat.

The double-sided adhesive sheet thus prepared was bonded to the glass plate on the side of the double-sided adhesive sheet provided with the adhesive having a small amount of the crosslinking agent (0.5%). Since the amount of the crosslinking agent was small, a pressure-sensitive adhesive having high adhesive strength was obtained. The BOPP side containing the printed image was also turned to the glass substrate.
